Characterization Of Parp1-Dependent Poly-Adp-Ribosylation Of Sprtn, Quincee Simonson
Characterization Of Parp1-Dependent Poly-Adp-Ribosylation Of Sprtn, Quincee Simonson
Electronic Theses and Dissertations
DNA-protein crosslinks (DPCs) are a type of DNA lesion that form when proteins become covalently linked to DNA. It is estimated that replicating cells experience approximately 6,000 DPCs per day per genome during exponential growth (Ruggiano & Ramadan, 2021). If left unrepaired, DPCs can be lethal to cells. For this reason, cells have evolved multiple pathways to repair or bypass DPCs to survive. One such pathway involves SPRTN, a nuclear metalloprotease that plays a key role in the repair of DPCs through direct proteolysis (Lopez-Mosqueda et al., 2016; Vaz et al., 2016). Once SPRTN degrades the bulky protein component of …
Understanding Human Gut Bacterial Interactions And Their Role In Colonization Resistance Against Clostridioides Difficile Using Mini-Bioreactor Array And Caenorhabditis Elegans As Model Systems, Achuthan Ambat
Electronic Theses and Dissertations
Although fecal transplantation has shown to be effective against Clostridioides difficile infection (CDI), key species responsible for colonization resistance still need to be better identified. There needs to be more understanding of the rules governing the development of a healthy microbiome upon transplantation. The bottom-up approach of assembling simple to complex communities in model systems such as bioreactors is one of the ways to approach this problem. Studying synthetic communities with less complexity can yield a system-level understanding of microbial interactions. In the first study, we assembled a synthetic community of 14 bacterial species belonging to the core human microbiota …

C3 And C4 Grass Dominated Plant Communities Differ In Response To Future Larger And Less Frequent Rainfall, Zigeng Chen
Electronic Theses and Dissertations
Climate change is leading to larger and less frequent rainfall in the Northern Great Plains (NGP). We ask if this change in rainfall would influence carbon (C) and nitrogen (N) cycling in the NGP. First, we collected soils from C3 and C4 grass dominated plant communities from western South Dakota and conducted an incubation experiment to explore the effects of soil water content (SWC) and temperature on soil respiration (Rs) and N mineralization rate (ΔIN). Second, we conducted a three-year rainfallmanipulation (RaMP) experiment with two distinct rainfall regimes (frequent/small and infrequent/large events with constant total monthly precipitation) and two grasses …
Chimeric Antigen Receptor T-Cell Therapy In Cancer, Brian Stahl
Chimeric Antigen Receptor T-Cell Therapy In Cancer, Brian Stahl
Biology and Microbiology Graduate Students Plan B Research Projects
The development of immune-checkpoint-inhibitors (ICIs) has led to promising advancements in the treatment of patients with cancers, leading with the use of cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) as a negative regulator of T cell activation in the mid-1990s. With the discovery of two ligands for program cell death protein-1 (PD-1) and promising checkpoint blockades in 2010, this sparked a cascade of hallmark immunotherapy drug patents, focusing on the mechanism of anti PD-1 and anti PD-L1 antibody inhibitors. Since then, chimeric antigen receptor (CAR)-engineered T (CAR-T) cells have emerged into the immuno-oncologic scene for treatment of hematological malignancies. These genetically …
A Review Of T1d: Prevalence, Current Therapies, And Cellular Therapies For The Future, Fahd Nazir
A Review Of T1d: Prevalence, Current Therapies, And Cellular Therapies For The Future, Fahd Nazir
Biology and Microbiology Graduate Students Plan B Research Projects
Type 1 diabetes (T1D) is a chronic autoimmune disease that is characterized by the destruction of pancreatic β-cells and therefore, creating an insulin deficiency within the body. A deficiency of insulin within the body disrupts homeostatic glucose control leading to hyperglycemia and therefore, the need for exogenous insulin. Global incidence of T1D has been increasing for several decades and if current trajectory trends continue, incidence could double in the next year. In addition, diabetes is the seventh leading cause of death in the United States. Current therapies for the treatment of T1D include insulin injections, insulin-pump therapy, pancreatic transplant, and …

Alzheimer’S Disease: An Overview And Current Phase 3 Disease-Modifying Biologic Treatments, Haley Jahnke
Biology and Microbiology Graduate Students Plan B Research Projects
Alzheimer’s Disease (AD) is a degenerative brain disease caused by cell damage leading to brain changes such as amyloid plaques and neurofibrillary tangles. Alois Alzheimer was a clinical psychiatrist and neuroanatomist in Germany who first discovered Alzheimer’s Disease through microscopic viewing of Auguste D’s brain. Through more research following Dr. Alzheimer’s death, they began to stage AD. The six stages are: pre-clinical, mild, moderate, moderately severe, severe, and very severe. The current treatments approved by the FDA work to slow the progression of AD, rather than modify the disease. There are currently three Disease-Modifying Biologic clinical-trial drugs on the market …

Modeling The Flow And Creep Compliance Properties Of Ice-Cream Mixes, Hiran Ranaweera
Electronic Theses and Dissertations
This work documented the influence of the protein source (MPC80 and WPC80), protein content (4-12%), and temperature (5-35ºC) on the rheological behavior (flow curve, frequency sweep, and creep-recovery) of ice-cream mixes (ICM). For each protein source, the viscosity of the ICM was satisfactorily modeled (𝑅2>0.98, 𝑅2 𝑎𝑑𝑗>0.98, and E0.99), while the recovery phase was represented by an empirical model. The percentage of recovery (%R) of the ICM significantly decreased with the protein content.
Characterizing The Lir Domain Of Abin1 And Identifying Its Role As A Regulator Of Mitophagy, Andrew Rhiner
Characterizing The Lir Domain Of Abin1 And Identifying Its Role As A Regulator Of Mitophagy, Andrew Rhiner
Electronic Theses and Dissertations
A20 Inhibitor of NF-κB (ABIN1/TNIP1) is a known regulator of TNFα signaling induced cell death and inflammation. The regulatory activity has been attributed to ABIN1’s recruitment of the ubiquitin editing enzyme TNF-α-induced protein 3 (TNFAIP3/A20) to Receptor-interacting serine/threonine-protein kinase 1 (RIPK1). The regulation of RIPK1 by ABIN1 and A20 relies on a third player, linear ubiquitin chain assembly complex (LUBAC), which is involved in the recruitment of ABIN1 to RIPK1. Loss of LUBAC or ABIN1 is embryonic lethal, but loss of A20 is not embryonic lethal. The embryonic lethality due to loss of ABIN1, paired with the lack of lethality …
Development Of Genomic Resources In Vitis Riparia For Discoveries On Pre- And Post-Transcriptional Molecular Regulators Of Early Induction Into Endodormancy, Michael Robben
Electronic Theses and Dissertations
Grapevine is one of the most important fruit crops in the world, responsible for billions in global sales annually. The largest threat to grapevine and other crop production is global climate change resulting human activities. This brings unpredictable and drastic changes in ambient air temperatures to many climates in which grapes are grown. Lower temperatures and inclement weather are already responsible for millions in lost revenue due to tissue damage of established plants. Thus, protecting grapevine crops from weather-related damage is the biggest concern to growers aside from pathogen- and diseaserelated crop damage. The primary mechanism for winter survival in …

Leveraging Queueing Theory To Develop Advanced Synthetic Biological Circuits, Prajakta K. Jadhav
Electronic Theses and Dissertations
The complexity and redundancy in the network topology of the cell hinder our understanding of the natural system, making it challenging to engineer living organisms with the desired functionality. The long-term goal of synthetic biology and bioengineering is to engineer cells to perform specific functions with increased robustness. The robust engineered systems can be easily applied to different species with the same outcome. An effective approach is a bottom-up approach where we tease apart the biological pathways and study them independently. Understanding the underlying mechanisms of biological pathways can be further applied to construct complex biological circuits that function similarly …
Identifying Adp-Ribosylation As The Biochemical Signal That Marks Dna-Protein Crosslinks For Sprtn-Dependent Proteolysis, Katelyn Hurley
Identifying Adp-Ribosylation As The Biochemical Signal That Marks Dna-Protein Crosslinks For Sprtn-Dependent Proteolysis, Katelyn Hurley
Electronic Theses and Dissertations
DNA-protein crosslinks (DPCs) form when proteins covalently attach to DNA. It is estimated that hundreds of DPCs form in our cells each day. Because these lesions are cytotoxic, mammalian cells have evolved multiple intricate repair systems to remove DPCs and restore genome integrity. One mechanism mammalian cells rely on for DPC repair is direct proteolysis by the metalloprotease, SPRTN. While it is known that SPRTN degrades a heterogenous array of DPCs, including both naturally occurring and chemically induced, how SPRTN selects DPCs amongst chromatin-associated proteins remains unknown. Our main objective is to determine how DPC repair is regulated. In Chapter …
Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi
Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi
Electronic Theses and Dissertations
Globally, canola is the second largest oilseed crop after soybean, which is processed for the commercial production of high value oil. The industrial processing steps for canola oil extraction include preprocessing (cleaning, pressing, flaking, and cooking), mechanical pressing, and/or organic solvents. This process results in large quantities of protein-rich (~ 40% dry basis) meal as a co-product. The meal is used partially in animal diet (<30% inclusion) due to high levels of antinutritional factors (ANFs) such as high fibers, phytic acid, and glucosinolates, and low metabolizable energy. Thus, this research was designed to examine various bioprocessing technologies (i.e., traditional sprouting, solid state fermentation, submerged state fermentation, co-culture fermentation, mild pretreatments, and their combinations) for possible advancement in canola use. Canola seed sprouting for 6-day period led to an increase in protein content and a reduction in ANFs and oil content of sprouts compared to ungerminated seed. Subsequent submerged state fermentation of 6- day old sprouts using three different strains (Aureobasidium pullulans, Trichoderma reesei and Neurospora crassa) further increased protein content and lowered ANFs. Solid-state fermentation of 144 h old sprouts using A. pullulans, N. crassa and T. reesei enhanced the protein content and reduced ANFs of sprouts. Sprouting canola seed for three days helped in hull removal, leading to high protein meal accompanied by low fiber and phytic acid level. Three-day seed sprouting had no effect on oil yield, but free fatty acid content was higher compared to seed oil. Co-culture fermentation of HECM under solid state process showed maximum reduction in fiber content with co-culture of A. pullulans and N. crassa while a combination of A. pullulans and T. reesei promoted the highest GLS and phytic acid reductions compared to other combinations, which indicated the advantage of coculture inoculation over monoculture in terms of ANFs reduction. Mild pretreatment of HECM using deionized water resulted in washed HECM (WHECM) with lower soluble sugars and GLS compared to untreated HECM, whereas protein and amino acid were concentrated due to the removal of soluble components. WHECM compared to HECM showed higher protein digestibility when fed to rainbow trout. Subsequent mono- and coculture fermentation of HECM and WHECM under submerged process resulted in higher protein and amino acid content and lower ANFs levels compared to uninoculated controls. The results of cellulase, endoglucanase and β-glucosidase activity indicated the crucial role of used substrates, fungi, fermentation modes (solid state/submerged stated) and inoculation methods (mono-/co-culture) on enzyme activities.

The Relationship Between Land Use Change And Disease Prevalence, Allison Bjornstad
Biology and Microbiology Graduate Students Plan B Research Projects
Zoonotic disease outbreaks are becoming more novel and are increasing in frequency. This increase can be partially attributed to land use changes including deforestation, urbanization, and cultivation. Land use change alters disease prevalence by causing an increase in contact rates between disease hosts and humans. Land use changes also alter species compositions in the area to contain more competent disease hosts. Each pathogen can react to these changes in different ways. The specific reactions that each pathogen has to land use changes should be further researched so proper mitigation steps can be taken. Once the effects of land use change …
Polycystic Kidney Disease: An Examination And Review Of Disease Type, Presentation, Treatment, And Prognosis, Zoey Mann
Biology and Microbiology Graduate Students Plan B Research Projects
Polycystic Kidney Disease (PKD) is a ciliopathy that primarily presents as renal cysts. Inherited as either a dominant (ADPKD) or recessive (ARPKD) mutation, PKD is one of the most commonly inherited kidney diseases. ADPKD is caused by the inheritance of a mutation in either PKD1 or PKD2, which code for the polycystin-1 and -2 proteins, respectively. The less severe form of PKD, ADPKD is typically adult-onset, with the possibility of extremely late-stage presentation. In addition to renal cysts, hepatic and pancreatic cysts are common, as well as other non-cystic symptoms including headache and hypertension. ARPKD is caused by the inheritance …

Current And Future Perspectives In The Treatment Of Fracture Nonunions, Zebadiah Nelson
Biology and Microbiology Graduate Students Plan B Research Projects
Fracture nonunions comprise one of the serious clinical complications in orthopedics. Fracture nonunions result when the time to union is greater than 6 to 9 months. It is estimated that approximately 5% to 10% of all fractures progress to fracture nonunion due to a host of complicating patient variables and risk factors. New scoring systems have emerged which help in directing the treatment strategies. Fracture nonunion management should be directed toward maintaining the diamond concept which introduces osteogenic cells lines, an osteoconductive scaffold for those cells to grow, as well as the necessary growth factors, and a stable mechanical microenvironment. …

Electrical Sensing In Non-Excitable Cells To Promote Galvanotaxis And Tissue Survival, Anyesha Sarkar
Electronic Theses and Dissertations
Weak DC fields have been shown to induce polarity, cell migration and cell proliferation in 2D cultures in vitro. To understand the mechanism by which non-excitable cells sense such weak EFs, we have investigated the mechanism of cathode-directed water flow (electro-osmosis) in the boundary layer of cells by reducing it with neutral, viscous polymers. Our results indicate that low molecular weight polymers decrease cathodal migration and promote anodal migration in a concentration dependent manner. High molecular weight polymers do not affect directionality and can be explained using porosity and hydraulic permeability between the polymers. These results provide the first evidence …
